Dark Horse Comics has formally announced the new Groo maxi-series for next year. It's called Groo: Friends and Foes and here's the description of the first issue…
Each month of this year-long series, Groo and his faithful pooch, Rufferto, encounter a different acquaintance — or enemy — with the usual dire consequences! In #1, Groo crosses paths with Captain Ahax, the seaman with the world record for most ships sunk by the all-time stupidest character in comics! Brought to you by the award-winning team of Sergio Aragonés and Mark Evanier! Eisner-winning letterer Stan Sakai and colorist Tom Luth round out this all-star team!
Not much more to add to that. Each month of 2015, you get a new issue of Groo. We're working away on it now…already finished up through #4. The stories, by the way, are not really continued but they are connected. That is, you'll want to read them in the proper order and if you do, you just might see an interesting sub-plot develop. Gee, it's fun to be doing this again. Hope it shows through.
